JOHN \VASHINGTON FREE, OF BOSTON, MASSACHUSETTS, AND MICHAEL A. BARBER, OF NORWICH, CONNECTICUT.

MALT-STIRRING MACHBNE.

SPECIFICATION forming part of Letters Patent No. 413,138, dated October I5, 1889.

Application filed February 4, 1889. Serial No. 298,633. (No model.)

To all whom it may concern: pulleys fare double-flanged pulleys in order to Be it known that we, JOHN XVASHINGTON allow of the engagement of thehook 9 (shown FREE, of Boston, in the county of Suffolk and in Fig. 3) with the chain. This hook g is at- State of lllassachusetts, and MICHAEL A. BAR- tached to the inner carriage G, in which ro- 5 BER, of Norwich, in the county of New Lon tates the stirrer-shaft Z). The outer end of the don and State of Connecticut, have invented stirrer-shaft is carried by another carriage h,

a new and .useful Improvement in a Malt the details of which are shown in Fig. 5. The

Stirring Machine, of which the following is a inner end of the stirrer-shaft h is mounted in specification, reference being had to the aca yoke H, which yokc is pivoted in a sliding IO companying drawings, forming a part of this block 11', and the shaft Z) carries a bevel-gear specification. 7t, which meshes into another bevel-gear h,

In the drawings, Figure 1 is a plan of the which passes through the axis of the block apparatus at one end, showing the actuating H and is provided on its lower end with a mechanism. Fig. 2 is a vertical section on sprocket-wheel 7L2. The block H slides to 15 the line 00 0c of Fig. 1. Fig. 3 is a vertical and fro lengthwise of the machine in ways 1. section transverse to Fig. 2 and on the line y A sprocket-chain K, shaped in cross-section y of Fig. 1. Fig. 4 is an enlarged view of the like the double obelisk of the printer, as carriage and hook shown in Fig. 3, and is shown in Fig. 2, is run from the main shaft taken on the line .2 z of Fig. 1. Fig. 5 is an E and actuates the sprocket-wheel 72, and 2o enlarged View of the carriage and chain upon drives the bevel-gearing h h, causing the the exterior of the wall of the machine, shown shaft (9 to revolve. Another chain L upon the in Fig. 1, andis taken on the line to w of Fig. 1. exterior of the machine engages with the car- It often happens in erecting malt-making riage b and moves it along, being geared in machines that it is desirable to have them obconnection with the main shaft to run at the 25 long rather than circular, and it is also desirsame rate as the chain F. Stops Y; are arable that the work of the machine should be ranged at the ends of the ways I. It will be continuous and in one direction of travel inseen by this arrangement that as the chains stead of reciprocating. It is to adapt the F and L move at the same rate the traverse mechanism to these conditions that this maof the stirring-wheel B along the sides of the o chine has been devised. apparatus will, so long as the sides are A is the malting-floor.

This shaft transmits its the shaft h around the geometrical center of power by a bevel-wheel E and a correspondthe curved end of the floor A until the caring bevel-wheel upon the opposite side of the riage G has been put into a position to engage 9o 40 axis of the machine to bevel-gears mounted with the chain F upon the opposite side of upon short shafts, which are shown in the the machine from its first position, when the drawings, Fig. 3, and lettered E. These short stirring-wheel will travel down the second shafts E, armed with bevel-gears at top and straight side of the floor in the reverse direcbottom, engage the bevel-gears E (shown in tion from that in which it traveled up the 5 Fig. 1,) running one of them in one direction straight side on which it was first engaged. and the other in the other. These bevel-gears The ways I carry guides 01 for presenting the E as shown in Fig. 3, are provided with chain K to the sprocket-wheel h in a proper sprocket-arms c, which sprocket-arms c serve position. to engageachain F. This chain F, as shownin In this machine, when employed for the I00 50 Fig. 2, has flanges which serve to guide it sprouting of malt, it is not proposed to employ over the guide-pulleysf of Fig. 3, which guidethe perforated floor which has been used in the patent apparatus of Which this is an improvement, although it does require While sprouting to be occasionally stirred. Consequently, as a machine of this sort-an oblong machine-Would present a greater surface of malt for the action of one stirrer than a machine witha circular floor, it is probable that a machine of this description would be better adapted for the sprouting operation than for the drying operation, and therefore Would preferably be made with a close floor. In such case the floor Would be made of hydraulic cement, which Would retain moisture.

Having thus described the invention, What We claim, and desire to secure by Letters Patent, is-

1. In a malting-machine, a malting-floor oblong in shape, having parallel sides and semicircular ends, the straight sides of said Walls equal in length to each other, and the curved sides of the inner and outer Walls being concentric With each other, in combination With the stirring-drum B, mounted on the two shaft-carriages b and G, the inner endless chain F, and. outer endless chain L, operating the shaft-carriages and drum, and the reciprocating shaft-carriage H and its Ways I, carrying the inner end of the stirring-drum shaft, substantially as described.

2. In an oblong malt-machine, the combination of the shaft-carriage Gr, having hook g, with the endless chain F, engaging said hook, and means for operating said chain, substantially as described.

3. In a malt-machine, the combination of the carriage H, the yoke H, pivoted in said carriage, bevel-gear h and sprocket 71 having bearing in said carriage, shaft 5, mounted in said yoke and carrying bevel-gear h, which engages the bevel-gear h, and the operatingchain K, substantially as described.

4. The combination of the inalting-floor having semicircular ends, with the stirringdrum B, the pivoted yoke H, and the exterior driving-chain L, substantially as described.
